polished magnesium metal test specimen for hydrolytic and thermal stability testing by SAE AS1241

SAE AS1241 Hydrolytic & Thermal Stability Test Specimen Set

These metal test specimens are used in SAE AS1241D §4.3 hydrolytic stability testing and in SAE AS1241D §4.4 thermal stability testing. Each test specimen is 1" x 1" x 0.062" with four 1/16" holes drilled at each corner of the specimen. SAE AS1241 requires ten specimens made from steel, cadmium, aluminum, magnesium, silver, copper, and titanium (alloys listed below). The specimens are polished (except for the cadmium metal specimen) and cleaned before testing. The specimens are tied together in two parallelogram assemblies per Figure 4 in SAE AS1241D. These specimens are individually packaged (not assembled) and are ready for use in the laboratory.


Metal alloys required for SAE AS1241 specimens:

  • Steel (AMS 6350)
  • Steel (AMS 6280 or AMS 5044)
  • Cadmium Plate (AMS-QQ-P-416 Type I Class 2)
  • Aluminum (AMS 4035 or AMS 4045) (two in each set)
  • Magnesium (AMS 4375, AMS 4376, or AMS 4377)
  • Silver (ASTM B700)
  • Copper (AMS 4500)
  • Titanium 6Al-4V (AMS 4911)
  • Titanium 3Al-2.5V (AMS 4944)
